This is an onion root tip at low power (100x). The cells are too small to distinguish individual phases. What phase do most of the cells appear to be in?

Interphase

Explanation:

The phase in which most of the cells appear to be in is interphase.

This is so because cell's life is spent more in interphase and in this phase growth of cells and at the end their replication takes place. So cells get more time in interphase to grow and replicate, which makes more cells to appear to be in.

Hence, the correct answer is "Interphase".

phylogenetic tree is the tree of life or evolution tree. it shows the different branches of evolution. the sequence goes like tissues - coelom - backbone - endoskeleton - segmentation

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
